1. Field of the Invention
The present invention relates generally to audio cassette adapters and, more particularly, to an audio cassette adapter with cable storage in the body of cassette.
Audio from portable playback devices (e.g., CD player, MP3 player, etc.) can be heard through a vehicle's cassette deck using an audio cassette adapter. These audio cassette adapters typically include a standard ⅛″ male connector that is coupled to a cassette shell at the other end of a cable. The male connector can then be inserted into a headphone port of a portable playback device such as an iPod. Through this connection, audio from the portable playback device can be delivered to a vehicle's stereo system through the cassette player. An advantage of such an arrangement is that it leverages an existing installed base of cassette players in today's vehicles.
One of the disadvantages of conventional audio cassette adapters is the storage of the cable and connector. When the connector is not in use, the cable and connector will typically hang from the audio cassette adapter in such a way that is unsightly. This is especially the case should the audio cassette adapter be left half inserted in the cassette deck. The unappealing aesthetics of such a solution therefore produces a deterrent for users that are looking for a low-cost mechanism to connect portable playback devices to vehicle stereo systems. What is needed therefore is an audio cassette adapter that can store a portable playback device connector and associated cable in an unobtrusive manner.
An audio cassette adapter with cable storage in the body of cassette, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
In order to describe the manner in which the above-recited and other advantages and features of the invention can be obtained, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Various embodiments of the invention are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the invention.
Portable playback devices have risen greatly in popularity due to the success of products such as the iPod. Over a hundred million of such devices have already been sold into the consumer market. Due to their large storage capacity, entire CD collections can be stored on such devices. Coupling of these portable playback devices to a vehicle's stereo system produces tremendous benefits to the user in obviating the need for the transport and handling of individual CDs.
One of the methods of coupling a portable playback device to a vehicle's stereo system is an FM transmitter. While these FM transmitters can produce reasonable sound quality, this solution does rely on the identification of clear FM channel space in the area of use. Users must therefore perform a sequential channel search by tuning both the FM transmitter and the FM receiver through a set of potential channels. Notwithstanding these setup issues, the use of FM transmitters may face further constraints due to the increasing government regulation of such radio transmissions.
Another method of coupling a portable playback device to a vehicle's stereo system is through a wired connection. Here, a cable having standard ⅛″ male connectors on each end can be connected to the headphone jack of the portable playback device and an Aux In port of the vehicle's stereo system. This simple solution provides a direct mechanism for coupling audio output signals from the portable playback device to the stereo system. A disadvantage of this solution, however, is the relative nonexistence of such Aux In ports in today's vehicles. Only within the last one to two years have vehicle manufacturers begun to include Aux In ports on their stereo systems. If the user does not have a newer model vehicle, then the user would need to replace a portion of his vehicle stereo system with a CD or tape player that includes an Aux In port. As would be appreciated, reinstalling a vehicle stereo system is both expensive and time consuming.
A third method of coupling a portable playback device to a vehicle's stereo system is via an audio cassette adapter. In this solution, audio from the portable playback device is delivered via a wired connection to a tape head contained within the audio cassette adapter. The vehicles cassette player would then read the audio signals from the tape head. Audio cassette adapters are well known in the art. An example of an audio cassette adapter is provided in U.S. Pat. No. 6,941,180 to Fischer et al., which is incorporated herein by reference in its entirety.
Audio cassette adapters typically include a standard ⅛″ male connector that is coupled via a cable to a cassette shell. The male connector can then be inserted into a headphone port of a portable playback device for delivery of audio signals. Audio cassette adapter cables need to be sufficiently long (e.g., two to four feet) to plug into the portable playback device. In one solution, the cable is a fixed length cable. This solution is aesthetically unpleasant since the cable and connector would dangle from the audio cassette adapter when not being used. This unpleasant look would exist even if the audio cassette adapter was coupled to a retractable mechanism that shortened the amount of cable that dangled from the cassette adapter shell. Even with such a retractable solution, a part of the cable, the retractable mechanism, and the connector would still dangle from the cassette adapter shell. As will be described in greater detail below, one of the features of the present invention is the storage of the cable and connector in the body of the audio cassette adapter housing, which thereby eliminates the dangling of the cable and connector.
In the present invention, it is recognized that while an Aux In port provides a simple solution, audio cassette adapters will remain popular due to the dearth of vehicle stereo systems that support Aux In ports. It accordance with the present invention, an audio cassette adapter is provided with improved aesthetics such as the elimination of dangling cables and connectors, which thereby enhances the desirability of the audio cassette adapter to the consumer market. As will be described in detail below, it is a feature of the present invention that an audio cassette adapter can be designed that supports the storage of both cable and connector in a non-obtrusive manner. This non-obtrusive storage enables the audio cassette adapter to appear as any other cassette in the vehicle.
As noted, one of the issues of having a cable extend from the audio cassette adapter is the storage of that cable. Fixed length cables would often be manually wound around the audio cassette adapter for storage. Not only is this inconvenient to the user, but it is also prone to becoming tangled with other wires or other components in storage. It is a feature of the present invention that the manual winding of the cable is eliminated using a retractable mechanism. Significantly, this retractable mechanism is built into the audio cassette adapter to further reduce the amount of external components that can complicate the storage process.
In the embodiment of
In the embodiment of
The operation of the cable retraction mechanism is illustrated in
In the illustration of
Just as the number of contacts used is implementation dependent, the type of cable used would also be implementation dependent. In general, any cable having the desired number of conductors and that is capable of being wound can be used. As would be appreciated, the relative thickness of the cable can significantly influence the length of cable that can be effectively wound into a cable winding having a sufficiently small diameter to fit into the cassette adapter housing. As such, in one embodiment, a thin tape-like cable is used.
Returning to the embodiment of
As has been described, audio signals originating with a portable playback device can be coupled to the audio cassette adapter via a retractable cable mechanism contained within the audio cassette adapter. The retractable cable mechanism eliminates the need for the user to manually wind the cable for storage. The problem still remains, however, of storing the connector that is attached to the cable in a convenient and aesthetically pleasing manner.
The present invention addresses the connector storage issue by accommodating such storage in the cassette adapter housing itself.
In the embodiment of
In one embodiment, cable 620 is maintained in grooved channel 640 via a tension-producing element in the audio cassette adapter. Examples of such tension-producing element include the retractable mechanism described above, a spring, etc. It should be noted that when a female connector is used, the cable need not be supported by a retractable mechanism. This results since the portable player device would likely interface with the female connector in the same way that it would interface with an Aux In port (i.e., using a male-to-male cable). One of the benefits of using a retractable cable mechanism with a female connector is in a simpler manufacturing process that is based on a cassette adapter design that can be selectively coupled to either a male or a female connector.
In one embodiment, an audio cassette adapter is designed with multiple storage recesses. These multiple storage recesses would enable the user to selectively determine which storage recess would be used for the connector depending on the particular type of cassette player used. The remaining storage recess can then be filled with a plug in the shape of the storage recess to fill the unused storage recess. In one embodiment, an unused storage recess can be configured with a garage door that can be closed to cover the storage recess. In another embodiment, a further connector can be stored in an unused storage recess that can convert a male connector to a female connector.
These and other aspects of the present invention will become apparent to those skilled in the art by a review of the preceding detailed description. Although a number of salient features of the present invention have been described above, the invention is capable of other embodiments and of being practiced and carried out in various ways that would be apparent to one of ordinary skill in the art after reading the disclosed invention, therefore the above description should not be considered to be exclusive of these other embodiments. Also, it is to be understood that the phraseology and terminology employed herein are for the purposes of description and should not be regarded as limiting.
